Abstract

PURPOSE:To simultaneously record all photographing data in an arbitrary film by storing successively photographing data of every frame and recording them in a film. CONSTITUTION:A CPU 30 reads 42 a DX code of a cartrige at the time of loading a film and decides whether photographing data is recorded at the time of reaching what ordinal number of frame. Thereafter, whenever a release 43 is depressed, the CPU 30 reads in a date which is set to an output part 36, and stores photographing data such as a date, a shutter speed, a diaphragm, a focal distance, an exposure correction quantity, etc., in each area 32a - 32e of a RAM 32 at the time of photographing. Subsequently, when it is decided to reach a frame for imprinting the photographing data, the CPU 30 inhibits a signal input from the release 43, displays automatically the data in the areas 32a - 32e on an LCD 2, brings an illuminating plate 3 to light emission and exposes the photographing data to the film.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a photographic data recording device that records photographic data set during photographing on the film itself.

[Prior Art and its Problems] Recently, cameras that are designed to imprint the date at the time of photographing are commonly used.

By the way, depending on the photo, it may be necessary to record not only the date but also the shooting data for each photo, such as shutter speed, aperture, focal length, exposure compensation amount, etc. The photographer takes notes such as a notebook for each shoot.
The reality is that they are written on paper that has nothing to do with the camera or film. However, this method was extremely uncertain as there was a risk of losing the recording paper and the recording itself could be forgotten.

Various methods can be considered for recording such photographic data.

The first method is to record the photographic data for each frame, as in the case of conventionally imprinting the date. However, this method has a major drawback in that a large number of numbers and the like are imprinted in the photograph, and although the photographic data is easy to see, the artistic quality of the photograph is significantly impaired.

The second method is to imprint the photographic data between the screens or in the vicinity of the verforation so as to avoid the drawbacks of the first method. This method has the advantage that the photographic data is not directly imprinted on the photo, so it does not affect the artistic quality of the photograph, but if it is reversally mounted, the photographic data cannot be seen. .

Next, the third method is to store this photographic data in a storage means such as an IC card, and view the stored contents on a playback device. However, this method has some problems in terms of storage stability. Furthermore, in order to solve this storage problem, it is possible to print out the stored contents using a printer or the like, but there is a possibility that it may become unclear which film the printed photographic data belongs to. In other words, there is no correlation with film.

[Object of the Invention] It is an object of the present invention to provide a photographic data recording device that does not have such various drawbacks and can be correlated with film.

[Summary of the Invention] The present invention solves the above problem by sequentially storing photographic data for each frame and recording this photographic data on the last frame of the film or any frame before it. It is.

In some cases, it may be composed of one display means and a control means for operating the exposure means. With such a configuration, it becomes possible to record all photographed data on an arbitrary film at one time.

Further, the recording means includes a film feeding means for feeding the film, a display means disposed in a direction perpendicular to the feeding direction of the film and displaying the shooting data stored in the storage means in a divided manner, and a display means for displaying the shooting data stored in the storage means. an exposure means for exposing the displayed photographic data onto the film; and when a frame at which the photographic data is to be recorded is reached, the display means and the exposure means are operated, and the display means and the exposure means are operated. and a control means for intermittently feeding the film by the film feeding means. With such a configuration, all photographic data for the film can be recorded on any frame by repeating the operation of intermittent forwarding of the film by the most shadow data several times. be able to.

It is connected. Therefore, by operating the data transfer mode switch 37, there is a mode in which only the date is imprinted each time a photograph is taken, like a shooting camera, and a mode in which only the date is imprinted on the last frame of the film or any frame before that. You can select a mode in which all photographic data is imprinted.

Further, a driver 39 for driving a take-up motor 38 constituting a film feeding means is connected to the CPU 30, and the driver 39 drives the take-up motor 38 according to instructions from the CPU 30. Furthermore, film movement confirmation data is input to the CPU 30 by a film movement detection device 34 that detects the rotation of a sprocket 33 that rotates as the film is transferred.

and the illumination plate 3 are operated by an LCD driver 40 . based on a command from the CPU 30 . It is operated by the driver 41.

Connected to the CPU 30 are a DX code reading unit 42 that reads the DX code of the patrone, and a release 43 that causes the camera to start a photographing operation.

The control section configured as described above operates as follows.

First, when the film is loaded, the CPU 30 reads the DX code of the cartridge using the DX code reading section 42, recognizes how many frames have been loaded, and determines the number of frames when the film is loaded. Decide whether to record the shooting data.

Thereafter, each time the release 43 is pressed, the CPU 30 reads the set date from the date data output section 36, and also records the date, shutter speed, aperture, focal length, exposure compensation amount, etc. when this photograph was taken. The photographic data is stored in each storage area 32a to 32e of each RAM 32.

Then, as the shooting progresses and the CPtJ 30 determines that it has reached the frame on which the shooting data is to be imprinted, the CPU 30 prohibits the input of signals from the release 43 and automatically
The photographic data stored in each storage area 32a to 32e of the RAM 32 is displayed on the LCD 2, and the illumination plate 3 is made to emit light to expose the photographic data displayed on the LCD 2 onto a film.

As a result, the photographic data is recorded on the film in the form shown in FIG. 8, for example.

The above is a case where shooting data for a film is recorded all at once.
An embodiment in which each frame is displayed on the LCD 2 of the rotation device 25 and exposed, and this is performed sequentially for the entire number of films, so that the shooting data for each film is imprinted (see Figs. 4 to 6). (Embodiment 1), photographic data can also be recorded on film in the form shown in FIG. In this case, the film is intermittently advanced by the winding motor 38 for each imprint width of the photographic data.

The above is an outline of the operation of the photographic data recording device according to the present invention, and below, the operation of each part will be explained in more detail based on FIGS. 9 to 11.

First, when you load the film and close the back cover, the CPU30
recognizes how many frames of film have been loaded from the DX code reading section 43 (step l). Step 2.3)
, and determines whether the current number of films has reached the first film from the end (that is, the final frame). That is, for example, if the film has 36 exposures, it is determined whether the 36th exposure has been reached (step 4).

Then, when it is determined that it is the last piece, CPLI30
The photographing data stored in each of the storage areas 32a to 32e of the RAM 32 is read out sequentially in the order of the darkest shadow and displayed on the LCD.
Activate the driver 40 and read all the captured data
The image is displayed on the CD 2 (step 5.6). In this case, the shutter cannot be released even if the release 43 is pressed.

When this display is completed, the CPU 30 operates the driver 41 to cause the illumination plate 3 to emit light, and the photographic data displayed on the LCD 2 is exposed and recorded on the film (step 7)e. 3 is a subroutine flowchart of step 3 of the main flowchart shown in FIG.

This flowchart is a flowchart for reading data.

When reading data, the CPU 30 sets the data reading counter N to 1 (step 10).
The first photographic data stored in each storage area 32a to 32e of the RAM 32 is sequentially read and the counter N is
Increment the value of by 1 (steps 11 to 16)

The reading operation ends (step 17).

FIG. 11 is a flowchart showing another embodiment of the photographic data recording device according to the present invention.

First, when you load the film and close the back cover, the CPU30
recognizes from the DX code reading section 43 how many first films have been loaded (step 18). Each time photography progresses, the photography data is recorded, and it is determined whether the current number of films has reached the first frame from the end (last frame). In other words, for example, if it is the first film, it will be determined whether or not it has reached the 24th frame (steps 19, 20, 21).Then, it will be determined that it is the last frame. Then, the CPU 30 sets the counter N to 1 and reads the first frame photographic data stored in each storage area 32a to 32e of the RAM 32 (step 22.23).In this case, The shutter does not release even if the release 43 is pressed.Then, the CPU 30
The CD driver 40 is operated to display the read photographic data on the LCD 2 of the rotation device 25 (step 24
). When this display is completed, the CPU 30
is activated to cause the illumination plate 3 of the rotation device 25 to emit light, and the photographic data displayed on the LCD 2 is exposed and recorded on the film (step 25). Next, the CPU 30 operates the driver 39 to drive the take-up morph 38 to advance the film by the recording width (1 pitch) of the shooting data.
Increment the value of counter N by 1 and step 2
The operations from step 3 to step 27 are performed for the number of images taken, and the recording operation of the photographed data is completed (step 26).

In the above-mentioned embodiments, the format in which photographic data is recorded for each frame is exemplified; however, the present invention is not limited to this, and the present invention is not limited to this, and may be, for example, a format in which photographic data is recorded for two frames at a time, or for three frames at a time. It's okay.

Further, in the above embodiment, the data imprinting mode switch 3
Although the explanation has been made on the assumption that the data imprinting mode switch 37 is turned on, the above operation will not be performed unless the data imprinting mode switch 37 is turned on.

Furthermore, if the data imprinting mode switch 37 is turned on when the last frame has been reached, the shooting data will be recorded, and if it is not turned on, the normal shooting will be performed by the release 43. good.

[Effects of the Invention] As is clear from the above description, according to the present invention, photographic data for each frame is sequentially stored, and this photographic data is transferred to the final frame of the film or any frame before it. Since the images are captured all at once, it is possible to obtain photographic data that correlates with the film and has good storage stability.
